WHEELBARROW-FRAME.

SPECIFICATION forming part of Letters Patent No. 758,824, dated May 3,1904.

Application filed February 20, 1903. Serial No. 144,233. (No model.)

To all whom it may concern:

Be it known that I, GEORGE C. CONE, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvements inWheelbarrow-Frames; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form part of thisspecification.

My invention has reference to a wheelbarrowframe,and has for its objectto provide a frame which shall be inexpensive and which shall combinemaximum strength with minimum weight.

The invention is especially adapted to be employed in the constructionof wheelbarrows used largely by masons, contractors, and the like, bywhom a wheelbarrow is required which is capable of sustaining a heavyload without danger of collapsing or breaking when lifted by means ofthe handles.

In the well-known construction of woodframe barrows the leg-supports andthe longitudinal bars of the frame are secured together by means of amortise-joint, the upstanding tongue upon each leg-support being clampedto the bar by means of a transverselyextending bolt. The longitudinalbars are obviously weakened by this construction, and I have found thatwood-frame barrows so constructed invariably break at the junction ofthe leg-supports with the longitudinal bars. To overcome this objectionand to provide a frame of great strength and rigidity which shall beinsured against collapsing under the the weight of a heavy load, myinvention is constructed and the same comprises the novel arrangementhereinafter shown and described, and illustrated in the accompanyingdrawings, in which Figure 1 is a perspective view of my improvedwheelbarrow-frame. Fig. 2 is an elevation, partly in section, of oneside of the frame, illustrating the construction; and Fig. 3 is atransverse section showing the relative arrangement of the metal andwood portions of the frame.

The frame proper comprises two longitudinal wooden frame-pieces 1,formed with handles 2, and between the forward ends of the same a wheelis adapted to be rotatably mounted.

3 represents bars of metal, preferably constructed of steel, L-shaped incross-section and adapted to be secured to the longitudinalframe-pieces, the webs of each bar lying in close contact with thebottom and one of the side faces of each frame-piece. Each metal bar isbent downwardly at 4: and formed with a return-bend, as at 5, and isagain bent angularly at 6. By thus bending the metal bars extremelyrigid leg-supports are provided for the frame.

7 represents bolts extending vertically through the horizontal web ofthe L-shaped metal bars and the longitudinal frame-pieces and adapted toclamp them together. By passing the clamping-bolts vertically throughthe wooden frame-pieces the strength of the latter is not impaired. Itis obvious that if said frame-pieces were perforated transversely thesame would be weakened and liable to break at the points where the boltspass therethrough.

8 is an L-shaped cross-bar secured between the leg-supports of the metalbars 3.

It will be apparent that a wheelbarrowframe constructed as hereindescribed will be extremely rigid and that the added rigidity providedby the metal bars clamped to the wooden frame-pieces as described willinsure maximum strength with minimum weight.

Although I have herein referred to L-shaped metal bars adapted to beclamped to the wooden frame-pieces, it is apparent that channel orU-shaped metal bars may also be employed, said U-shaped bars beingclamped to embrace the frame-pieces on the bottom and sides, theclamping-bolts being arranged to extend vertically upward through theU-shaped bars and the frame-pieces.

Having described my invention, what I claim, and desire to secure byLetters Patent,

In a frame for a wheelbarrow of the type set forth, the combination withthe pair of members, having handleforming portions thereon, providedwith a series of verticallydisposed bolt-receiving Openings therein, apair of members L-shaped in cross-section and supporting each of saidfirst-named members upon their horizontal lower face, said membershaving openings therein adapted to register with those of thefirst-named members, whereby securing means may be vertically receivedwithin the same, said members comprising a substantially U-shaped bodyportion forming legs for the frame, and forwardly and rearwardlyprojecting members extending substantially at right angles to the bodyportions the forwardly-extending portions being of greater length thanthe rearwardly-extending portions and an L-shaped brace member securingthe body portions of the said lastnamed members in fixed position,substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
